Agonist-specific patterns of beta(2)-adrenoceptor responses in human airway cells during prolonged exposure.

Background and purpose: beta(2)-Adrenoceptor agonists (beta(2)-agonists) are important bronchodilators used in the treatment of asthma and chronic obstructive pulmonary disease. At the molecular level, beta(2)-adrenergic agonist stimulation induces desensitization of the beta(2)-adrenoceptor. In this study, we have examined the relationships between initial effect and subsequent reduction of respo

Longitudinal clearance of seasonal influenza A viral RNA measured by real-time polymerase chain reaction in patients identified at a hospital emergency department.

Abstract To study influenza virus shedding during acute infection, viral load was longitudinally measured by quantitative PCR in nasal flocked swabs from patients with seasonal H3N2 influenza at a Swedish emergency department, including both hospitalized patients and outpatients. Influenza A was detected in 65/184 patients. Sampling was repeated every 3-4 days in 45 patients, with the aim of conti

Metabolism of sphingolipids in the gut and its relation to inflammation and cancer development.

Sphingolipids are abundant in the microvillar membrane of intestinal epithelial cells where they are essential for structural integrity and may act as receptors for toxins, virus and bacteria. Metabolism of dietary and membrane sphingolipids in the intestine generates ceramide, sphingosine, sphingosine-1-phosphate, and ceramide-1-phosphate, via the action of alkaline sphingomyelinase, neutral cera

'Piracy Culture in Greece: Local Realities and Civic Potentials

Departing from a critical perspective on intellectual property rights, this article investigates the popular phenomenon of free online file-sharing beyond its hegemonic framing as piracy. The article focuses on the civic potentials entailed in free and participatory culture of new media and ICT. A “civic” focus, in the context of free sharing, aims at assessing the potential of a democratic cultur

Instrumentalized History and the Motif of Repetition in News Coverage of Japan-Taiwan Relations

Examining the coverage in seven major Japanese and Taiwanese daily newspapers of a selection of events involving both societies in the first decade of the twenty-first century, this paper investigates the phenomenon of rhetorical instrumentalization of the past for present ideological purposes. The concerns of this study are the processes of dehistorization in Japanese and Taiwanese news and publi

Normalization of Illumina Infinium whole-genome SNP data improves copy number estimates and allelic intensity ratios.

BACKGROUND: Illumina Infinium whole genome genotyping (WGG) arrays are increasingly being applied in cancer genomics to study gene copy number alterations and allele-specific aberrations such as loss-of-heterozygosity (LOH). Methods developed for normalization of WGG arrays have mostly focused on diploid, normal samples. However, for cancer samples genomic aberrations may confound normalization an

Att förhandla litterärt värde – Sami Said och Väldigt sällan fin

This article aims to highlight how literary value is constructed today: how it is created and negotiated. It seeks to develop a perspective that considers the manifold and complex value­negotiation process. In accordance with Barbara Herrnstein Smith, the article argues that literary value is generated by a constant and continuous series of negotiations between production and sale: the institution

Complications associated with peripheral or central routes for central venous cannulation.

We undertook a review of studies comparing complications of centrally or peripherally inserted central venous catheters. Twelve studies were included. Catheter tip malpositioning (9.3% vs 3.4%, p = 0.0007), thrombophlebitis (78 vs 7.5 per 10 000 indwelling days, p = 0.0001) and catheter dysfunction (78 vs 14 per 10 000 indwelling days, p = 0.04) were more common with peripherally inserted catheter
